    Please read this portion carefully to avoid equipment damage or personal injury. Power Source The A6907 and A6909 can be used with AC power at frequencies from 50 Hz to 60 Hz and at voltages from 100 V to 240 V. Line Fuse Make sure that the proper line fuse has been installed before connecting the isolator to the power source.

  • Page 19: Power Cord

    WARNING. In order to prevent electrical shock, only plug the power cord into grounded three-wire outlets. Do not defeat the ground connection on the plug. The A6907 and A6909 power cords are three-wire grounded cords. The metal portions on the outside of the isolator are connected to the power-source ground by means of the ground wire in the power cord and plug.

    NOTE. In order to ensure the accuracy of measurements, self-calibration should be performed just before taking measurements. The A6907 and A6909 are equipped with a self-calibration function that automatically calibrates the offset and gain for each channel for maximum accuracy. After the isolator has been warmed up for 20 minutes, use the following procedure to perform the self-calibration: 1.

  • Page 42 This characteristic is sometimes called the “non-destructive .” On the A6907 and A6909, this value is 20 kV/ms. Therefore, the instrument can tolerate a common mode input signal with a slew rate less than this value.

  • Page 43: Figure 3-1: Normal And Common Mode Simplified Circuits

    On the A6907 and A6909, a CMRR value at 1 MHz is 55 dB (560:1). For example, when a sine wave signal of 1 MHz at 100 Vp-p is applied as a common mode input, a differential error signal of 180 mV p-p or less will be generated (when the isolator range is set to 100 mV/div).

  • Page 44: Gpib Programming

    GPIB Programming You can use a computer to control the A6907 isolator and make measurements. (You can also control the A6909 with option 10 installed.) With an oscilloscope that also can be programmed, the computer and isolator can form a complete, automated measurement system.
